• dyestuffs enable other classes of dyestuffs to be used, such as for example metalliferous complexes, acid dyestuffs, dyestuffs intended more particularly for dyeing polyester fibres, reactive dyestuffs, vat dyestuffs or fluorescent brightening agents.
• metalliferous complexes for example metalliferous complexes, acid dyestuffs, dyestuffs intended more particularly for dyeing polyester fibres, reactive dyestuffs, vat dyestuffs or fluorescent brightening agents.
• acid dyestuffs such as for example metalliferous complexes, acid dyestuffs, dyestuffs intended more particularly for dyeing polyester fibres, reactive dyestuffs, vat dyestuffs or fluorescent brightening agents.
• swelling agents or carriers may be mentioned: reduction of the brightness of the dyestuffs and of their yields; sublimation of the dyestuffs with a possible appearance of spreading around the printed patterns; precarious fixation of the dyestuffs, from which follows lack of fastness to wet tests; reduction in the dynamometric strength of the fibres; insufficient solubility or dispersiveness in water, which causes difficulty in removing them from the fabric by washing and defects in uni- 3,513,493 Patented May 26, 1970 ice formity; incompatibility with some thickeners, dispersing agents, surface-active agents or certain emulsions used in the printing pastes or the dyebaths; too great volatility, which causes loss of efficiency during thermal treatments.
• the present invention therefore has as its object an improvement in processes for printing, dyeing, discharging and optical bleaching of fabrics, threads, cards, films and other supports based on cellulose triacetate or cellulose diacetate.
• This new process is characterised by the fact that an acyclic compound containing at least one group, R and R' represent hydrogen atoms or CH:; groups, is used as a swelling agent or carrier.
• the catalyst may be, for example, an alkali metal or an oxide, hydroxide, alcoholate, hydride, cyanide or amide of an alkali metal.
• Quaternary ammonium hydroxides for example benzyltrirnethyl-ammonium hydroxide, or tertiary amines such as triethylamine, may also be used as catalysts if their basic character is sufficiently marked.
• the amount of catalyst to be used may vary from 0.01% to 5% of the weight of nitrile and the condensation temperature may vary within wide limits, preferably between the ambient temperature and the boiling temperature of the nitrile or the compound to be cyano-alkylated, and the reaction may be carried out under pressure.
• the carriers defined above may be used in proportions varying within wide limits. For example, for printing, 0.5% to 30% of the total weight of the printing paste, and for dyeing, 5 g. to 300 g. per litre, preferably 50 g. to 100 g. per litre of bath liquid may be used.
• materials based on cellulose diacetate or triacetate may be satisfactorily dyed or printed with plastosoluble dyestuffs, metalliferous complexes, dyestuffs intended more particularly for dyeing polyester fibres, vat dyestuffs, basic dyestuffs, acidic dyestuffs, reactive dyestuffs and fluorescent brightening agents, by incorporating compounds containing one or more groups in the printing paste or the dyebath.
• These carriers have swelling properties with respect to the fibre and solubilising properties with respect to the dyestuffs. They thus improve the diffusion of the molecules and conse quently the fixing of the dyestuffs.
• the acid dyestuffs could be fixed as easily and as firmly on fibres, such as for example cellulose acetate or triacetate, having an acid chracter and being slightly plastic.
